网站随机切换广告代码

网站如何实现刷下页面自动切换图片广告，小编也是寻找和测试了很久才寻找到，那么下面小编为你分享两种随机切换广告代码

代码一：这种代码形式是正对长按扫码方式，针对网站自动切换各种二维码形式所用的，代码如下，仅需复制把图片链接改成你自己的即可

<script language=javascript>

today=new Date();

jran=today.getTime();

function rnd() {

ia=9301;

ic=49297;

im=233280;

jran = (jran*ia+ic) % im;

return jran/(im*1.0);

};

function rand(number) {

return Math.ceil(rnd()*number);

};

document.write("<center>");

for(i=1;i<=1;i++) {

mynum=(rand(10)); //随机图片；

if(mynum == 1) document.write("<img src='https://mp.qunxuehui.com/images/01.png'style=' width:100%; height:x;'/>"); 

if(mynum == 2) document.write("<img src='https://mp.qunxuehui.com//images/02.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 3) document.write("<img src='https://mp.qunxuehui.com//images/03.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 4) document.write("<img src='https://mp.qunxuehui.com//images/04.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 5) document.write("<img src='https://mp.qunxuehui.com//images/05.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 6) document.write("<img src='https://mp.qunxuehui.com//images/06.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 7) document.write("<img src='https://mp.qunxuehui.com//images/07.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 8) document.write("<img src='https://mp.qunxuehui.com//images/08.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 9) document.write("<img src='https://mp.qunxuehui.com//images/09.jpg'style=' width:100%; height:x;'/>"); 

if(mynum == 10) document.write("<img src='https://mp.qunxuehui.com//images/10.png'style=' width:100%; height:x;'/>"); 

else {

document.write();

}

};

document.write("</center>");

代码二：这种代码是正对广告图片点击的，只复制把图片链接地址改成你自己的即可，下列代码当用户刷新一次，就会自动切换广告图片以及链接，让网站实现多广告变现

<script language=javascript>

today=new Date();

jran=today.getTime();

function rnd() {

ia=9301;

ic=49297;

im=233280;

jran = (jran*ia+ic) % im;

return jran/(im*1.0);

};

function rand(number) {

return Math.ceil(rnd()*number);

};

document.write("<center>");

for(i=1;i<=1;i++) {

mynum=(rand(10)); //随机图片；

if(mynum == 1) document.write("<a href =https://www.qunxuehui.com/ ><img src='https://www.qunxuehui.com/d/file/p/2021/08-24/9aebd2356a4f432909614af9aea0cf58.jpeg'style=' width:100%; height:x;'/></img></a>");
